Widely distributed, the best at Stations 2, 6 and 45. At the deep-water 

 Stations the form has a tendency to narrow, and to nrerge into L. gntcilis. 

 Spinous-based individuals occur at Stations 18, 19 and 36, at the last of which 

 the spine is almost as long as the neck. At Station 10 the costae are developed 

 very highly, standing out as wings. At Station 10 the examples have a very long
